I To all whom it may concern.

Be it known that I, ALBEN E. LUNDELL, a citizen of the UnitedStates,residing at New ork, in the county of Bronx and State of NewYork, have invented certain new and useful Improvements in ElectricSignaling ystems, of which the following is a full, 0 ear, concise,and'eXact description.

hls invention relates to signaling sys-- tems, and more particularly tosystems in which variably operable electromagnetic mechanisms controlthe actuation of desired signals.

vide newand improved arrangements fdr actuating a plurality of signalsdesignating digits, without the necessity of actuating signals whichwouldnot change the value of the desired numerical signal.

The drawing represents diagrammatically a signaling system, only so muchbeing shown of the circuits and mechanisms as is necessa I for a clearunderstandingof this invention. 7

Under the control of a sender, registering switches 10, 11 and 12 and asequence switch 13 may be set to control the operation of lamp signals14, 15, 16,17and18 respectively. The lamps and contacts, shown betweenvertical dotted lines above the registering and sequence V switches, arecontrolled by said switches respectively. Register 10 may be.adjusted'in accordance with the 100s, register 11 the 10s, and register12 the units digital numeral of the desired signal. The lamps whicharegrou ped in the same manner as the registers, will be actuated thusto display the desired number. The resting positions of the registersare indicated by letters and numerals.

he operation ofregistering and sequence switches, and ,of;senders, iswell-known in the art, and such devices of widely varying character maybe used for practising the present invention without departing from thespirit of the same. A complete description of a, preferred form of suchapparatus may be had from my Patent No. 1,168,319. of January 8,1916,filed August 22,1913.

After the sender has been adiusted for controlling the operation ofregisters 10, 11 and 12.,a11 impulse controlling circuit is closed fromground through contact 20. the Winding of a stepping ELECTRIC SIGNALINGSYSTEM.

Relay 22 becomes energized and closes a circuit from ground through itsfront contact bottom armature, contact 23 of sequence switch 13,conductor 24 and the power magnet of the 100s register 10 to groundedbattery. Under the control of a normal spring 25, register 10 is movedout of its N position.

The impulses representing the first digit having been sent out, contact20 is opened, whereupon relay 22 becomes deenergized. circuit isclosednow from ground through the upper back contact and armature ofthis Patented Mar. a, rare. Application filed December 22, 1915. SerialNo. 68,208.

Under the control of normalspring 36, sequence switch 13 is caused to move out of position 1 intoposition 2.

Contact 20 is again closed and relay 22 becomes again energized andestablishes a circuit from ground through its bottom front contactandarmature, sequence switch contact 37, conductor 38 and the power magnetof the 10s register 1 1.to grounded battery Under the control of normal39, this register is'moved out of its N position, When moving throughposition Ni, register 11 causes, in the same manner as has beendescribed in connection with register 10, the restoration of the senderby closing spring in parallel to grounded battery,

Register 11 remains in its1X position. Upon the deenergization ofrelayi22, circuit is closed fromground through the upper back contact and armature of relay 22, contact30-of register '12, contact 41 of register 11, sequence switch contact4C2, conductor 35 and the power magnet of sequence switch 13 -togrounded battery, for .inoving this switch out of position 2,-intoposition: 3.

Contact ,20 having been closed after "the sending out of the 110simpulses, relay 22 again becomes energized and causes the-clo sure ofva-Ycircuit from ground :through its bottom front contact and. armature,sequence switch spring Adandthc power magnetof register 12 vto groundedbattery, whereby, underthe control of normalspring 44, this1registerjis:inoved out o'flposition N. In each half position of thisregister a short-circuit ing impulse is sent through contact to magnet21, causingthis magnetuto stepthe sender until register 1-2 reachesposition 1. The impulse sending circuit is new constantly open vatcontact 20. Relay 22lbecomes deenergizedand closes a circuit firromground through its upper back contact and armature, contact 46'ofregister .12, sequence switch contact 34 conductor 35, and the powern agnet of sequence switch 13 to grounded .hattery, :for moving thisswitch a out of positiond nto position-,6.
